LOCKING DEVICE FOR VEHICLE AND OTHER WHEELS.

all classes of wheels, but particularly the wheels of road-vehicles, andhas for its object the production of a simple device which may bereadily attached to existing vehicles and which is very simple in itsoperation.

In carrying out this invention I attach a notched band on or slot thehub of the wheel, and on the axle I fit a clutch-gear consisting,preferably, of a bell-crank or lever suitably pivoted so as to engage(when desired) with the before-mentioned notches or slots and operatedby a handle in convenient reach of the driver or other occupant of thevehicle.

The wheel-lock may be applied to the rim of the wheel; but I prefer toplace it as already mentioned.

The details of the invention may be varied in several respects.

Referring to the drawings which form a part of this specification,Figure l is an elevation with one plate removed, showing the wheellocked. Fig. 2 is an elevation with one plate removed, showing thedevice out of action and the wheel free. Fig. 3 is a plan View showingplates bolted to axle.

A is the hub of the wheel; B, axle of vehicle; O, a notched band shrunkonto the hub.

Onto the axle are bolted two plates D and D. Pivoted' to one of thebolts is a bellcrank or double-armed pawl E. F is a spring pivoted to aspindle, which may be riveted or otherwise secured to the plates. Thisspring throws one end of the pawl into engagement with the notches onband C.

G is a tripper with square hole at heel for receiving a. square spindle,the ends of which Specification of Letters'Patent.

are rounded for pivoting into round holes in the plates, and one end ofthe spindle protrudes beyond the face of the plate, acting as a handlefor operating the tripper and which may be by a connecting-lever carriedup the side of the vehicle within reach of the driver, or the end may besquared off for receiving a key-lever. The locking end of the tripper isenlarged and has its edge straight, so that where said edge engages thelever it holds the said lever positively in its release from the notchesof the hub. When the tripper is turned in the direction as shown in Fig.2, it releases the pawl from the notched band C, and when turned in theopposite direction one arm of the pawl is thrust out and engages with anotch on hand O on the'revolving of the hub, thus securely locking thewheel.

The locking device is shown as applied to a spring-cart and fixed belowthe spring. As the springs and coupling form no part of this invention,reference to same is unnecessary. When used for light vehicles, it canbe placed on the axle between the spring and the hub and may be soplaced that the pawl Works on a horizontal plane to the axle.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In combination with a vehicle-axle, a hub thereon, having recesses, apivoted lever carried by the axle adapted to engage the recesses of thehub, a rotary eccentric trip for the lever adapted to release said leverfrom the notches, the contacting end of the trip being enlarged topositively hold the lever in its release and a locking-spring bearingagainst the lever.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
